Elon Musk unveiled Tesla's first electric semi-truck on Thursday evening at an event in Los Angeles that also included the surprise reveal of a new Tesla sports car. The new Roadster, which has the same name as the first electric vehicle produced by Tesla from 2008 to 2012, emerged from the back of one of the trucks at the end of a presentation that focused largely on the economic and performance needs of truck drivers. "The point of doing this is just to give a hardcore smackdown to gasoline cars," Musk said. "Driving a gasoline sports car is going to feel like a steam engine with a side of quiche." While the sports car provided a jolt of excitement for Tesla enthusiasts, much of the event focused on pitching the truck to truck drivers – customers with very different concerns than the average Tesla owner.

Has Tesla succeeded in creating a vehicle that reacts faster than its driver? A recently-surfaced dashcam video appears to show Tesla's autopilot mode predicting an accident moments before it actually happens. It currently takes hours to charge an electric car - but Elon Musk just hinted that Tesla's next-gen superchargers will be able to juice up an eve in mere seconds. Musk also confirmed plans for a new Tesla Roadster, which is expected to debut in 2019. Uber recently launched a fleet of self-driving cars in California, but the state promptly shut the experiment down.
